In point of fact the nature of your response and the personal attacks you've been engaging in only reveal one thing, that this subject has hit a nerve, and that you are unable to respond with any sense of maturity or decorum. This is generally a telling sign. When people don't have a good defence, they go on the attack.
I've spoken to plenty of Catholics who are more than prepared to acknowledge that the majority of the dogmas, customs, rites, and traditions that they associate with their religion do not date back to the first century, or any where near it. I think they'd be frankly embarrassed to know that a fellow believer states "literally nothing has changed".
